Google's rich results boost visibility, but implementing them is tricky. A developer shared hard-won lessons from adding JSON-LD to a Next.js project. The key is focusing on just a few essential Schema.org types like Organization, WebSite, and Article, avoiding the platform's overwhelming 800+ options.

Instead of scattering raw JSON, the author built typed React components. Using TypeScript ensures fields like datePublished are correct before deployment. This component-based approach keeps SEO markup organized and maintainable within a modern Next.js architecture.

The critical step is testing on a live URL, not just localhost. A common pitfall is using JavaScript's `toLocaleDateString()` instead of the required ISO 8601 format, which Google's validator rejects cryptically. After fixing issues, FAQ rich results appeared within two weeks on a product review site.
